Polaroid TDA-03211C
Recently I grabbed a Polaroid TDA-03211C from someone's curbside trash. There was also a tube-style computer monitor, but I let the other trash-pickers take that.
When plugged in, the LED light on the front of the TV changes from red to blue and the built-in DVD player spins for a short time before stopping (it is probably programmed into a ROM chip to search for a disc in the drive upon startup). The LED on the power board blinks at around 1 Hz.
Here we have a picture of [part of] the power board. Clearly the 10 microfarad 450 working volts DC capacitors need replacing, they are bulging (between the "TC18813F / RoHS" and "PROVIEW" silkscreens). All capacitors are "HEC" brand.
(Yes, this will take some time - I am busy with lots of work at my job, and around the house too.)
Should I remove the heatsink and replace the others?
